This could take a while, so I'll simply put the answer with the theorem I used to figure it out with.
<em>1) </em><em>45° - minor arc; </em>Central Angles/Arcs Theorem
<em>2) </em><em>180° - semi circle; </em>Diameter Theorem? (Whichever theorem states that the diameter separates a circle into two 180° semi circles)
<em>3) </em><em>75° - minor arc; </em>Angle Addition Postulate
<em>4) </em><em>105° - minor arc; </em>Angle Addition Postulate
<em>5) </em><em>225° - major arc; </em>Angle Addition Postulate
<em>6) </em><em>45° - minor arc; </em>Vertical Angles Theorem
<em>7) </em><em>135° - minor arc; </em>Angle Addition Postulate
<em>8) </em><em>240° - major arc; </em>Angle Addition Postulate
<em>9) </em><em>315° - major arc; </em>Angle Subtraction Postulate, i think? lol.
<em>10) </em><em>180° - semi circle; </em>Diameter Theorem or whatever it's called lol.
Additionally, I determined whether or not an angle was a major arc, minor arc, or semi circle with the knowledge that:
- minor arc - less than 180 degrees
- major arc - more than 180 degrees
- semi circle - is 180 degrees.
<em>Have a nice day, fam. Spread The Love. lol I'm tired after typing all this out :P</em>
